FlexCore Minibus
The Version 1.6 HeatNet board requires Minibus connections for FlexCore boilers with more than (1) heat exchanger. The
Minibus requires a serial data cable between each HeatNet Control board. The first and last Heat Exchanger must have the
minibus terminated for the bus to work properly. S1 would be placed in the ON position as indicated below for the front and rear
heat exchangers. The jumper, JS1 must always be in the position indicated (closest to S1). It is used for testing.
